latest stable livecd

The website says that the latest "stable" LFS livecd is
lfslivecd-x86-6.2-3.iso , but the Download mirror shows
lfslivecd-x86-6.2-4.iso , and even lfslivecd-x86-6.2-5.iso . So which is
really the latest stable version, and if it is lfslivecd-x86-6.2-.iso ,
then what are the others? I am relatively new to LFS, and do not want to
"experiment" with developmental versions (just learning is hard enough
as it is!)
